URL: http://www.poissonconsulting.ca/f/934446658. Background Each spring in the Lower Columbia River (LCR) below the Hugh L. Keenleyside Dam (HLK) and in the Lower Kootenay River (LKR) below the Brilliant Dam, thousands of Rainbow Trout spawn. Since 1992, BC Hydro has stabilized the spring discharge releases from HLK to protect Rainbow Trout redds from dewatering.

URL: http://www.poissonconsulting.ca/f/1498798685. Background Every fall, Kokanee from Kootenay Lake spawn in the Duncan-Lardeau system. Since 2008 aerial surveys have been conducted in the Lower Duncan River (LDR) to enumerate the number of kokanee spawners. The management questions are: What is the spawn run timing, fry emergence timing, and relative intensity of kokanee spawning in the Lower Duncan River?
